Find the number of triangles in the given figure.

8
10
12
14
Answer: Option
Explanation:

The figure may be labelled as shown.

The simplest triangles are AHG, AIG, AIB, JFE, CJE and CED i.e. 6 in number.

The triangles composed of two components each are ABG, CFE, ACJ and EGI i.e. 4 in number.

The triangles composed of three components each are ACE, AGE and CFD i.e. 3 in number.

There is only one triangle i.e. AHE composed of four components.

Therefore, There are 6 + 4 + 3 + 1 = 14 triangles in the given figure.

CFD is covered by 4 triangles. This changes the calculation by triangles covered by three components are 2 and four triangle components 2.

Is there any standard formula for solving these types of questions?

Just to concentrate the figure and count it's twice or thrice then you can solve it.

Nodes are vertices which are labeled as (A, B, . , I, J).

Such as: A is node similarly I is an internal node.
